The output voltage is the result of a 12 bit Digital to Analog conversion performed on the input data with a resolution of > 3 mV per step. Calibrate and test modes are available using the 2073 chassis front panel rotary switch. Loop-back test mode simulates the expected user data, which includes both Analog and RS-232 data outputs for stand-alone system verification. The IOC106 uses one DB9P input connector, one DB9S output connector and two BNC output connectors and operates up to 9600 BAUD. The input can also drive the Daisy Chain bus and the Global bus in the Model 2073 Chassis, enabling the user to create multiple copies of the input signal. The IOC106 requires two slots of the 14 available slots in the Model 2073 chassis.

These characters are converted to a 12-bit binary value and presented to a 12-bit digital-to-analog converter (DAC). The resulting analog voltage is in direct proportion to the numerical ASCII input. An error detection mode of operation is available that removes or smoothes adjacent readings under certain conditions. This error checking mode reports an error to the B LED and pulses the error output when a subsequent measurement is greater than 100.0 ASCII from the previous measurement. When this condition is encountered the previous measurement is held on both the analog and RS-232 outputs. TEST MODES The IOC106 includes the capability of generating test data which is used to verify operation of the card absent a data source. The test modes are selectable using the front panel rotary switch. Static test modes are fixed levels values that are internally applied to the DAC circuitry and the J2 output connector simultaneously. It is not necessary to disconnect a user input on J1 to run the static tests. Rotary switch position 8 puts the IOC106 into a dynamic test mode which is an increasing ASCII value ranging from 000.0 to 300.0 in 0.1 increments. The dynamic test data is present on J1 pin 3, which must be connected to the input of the IOC106 at J1 pin 2 when running in this test mode. 210 South 3rd Street, North Wales, PA 19454 Tel: 215-699-2060 Fax: 215-699-2061 E-Mail: firstname.lastname@example.org 4 5.10.05 APOGEE LABS, INC.
